Strontium is a silver white alkaline earth metal with a yellow luster. It is the second least abundant element in alkaline earth metals、 second only to beryllium. The elemental substance can be obtained by electrolysis of molten strontium chloride. Strontium is a trace element widely present in soil and seawater、 which has the function of preventing arteriosclerosis and thrombosis. Used for manufacturing alloys、 photocells、 fireworks、 chemical reagents、 etc. Isotope 90 strontium is radioactive with a half-life of 28.1 years and can be used as β Radiation source
Strontium is the second least abundant element in alkaline earth metals. In nature、 it mainly exists in a combined state、 with the main ores being celestite (SrSO4) and strontium siderite (SrCO3) Whether in the manufacturing process of reducing SrS with carbon and then reacting、 or in the soda treatment process、 celestite is the starting material for manufacturing SrCO3. Due to the ability of strontium carbonate to produce other Sr compounds、 it is used to purify Zn (remove Pb and Cd) for the production of ceramic permanent magnets、 and for the production of television fluorescent screens. It is the most important Sr compound. Sr (NO3) 2 is used for pyrotechnic devices、 SrO is used for aluminum smelting、 and Sr and SrCl2 are used for tooth repair. Sr (OH) 2 has long been used for the purification of molasses Metal strontium is used in the manufacturing of alloys、 photocells、 and lighting fixtures. Its compounds are used for making signal bombs、 fireworks、 etc Strontium-90 can be used β The radioactive source of radiation poses significant harm to the human body、 with a half-life of 25 years. It is produced by uranium in nuclear tests and inhaled by the human body in the form of dust、 causing radioactive damage to the human body Strontium 87m is released γ Radiation has certain applications in medicine. Introduce strontium-87m into the patient's body、 and after the bone is absorbed、 use a radiation detector to determine its position in the human skeleton and determine any abnormalities in the human body. Although the half-life of strontium-87m is only 2.8 hours、 it will be quickly discharged from the human body、 so the amount of radiation received by the human body is very small
